Example: For the following reaction, use the given rate law to determine the best answer for the reaction with respect to each reactant and the overall order. H2O2 (aq) + 3 I – (aq) + 2 H+ (aq)  --->  I3 – + 2 H2O (l)     Rate = k [H2O2]2 [I –]   a) H2O2 is 1st order, I – is 1st order, 2nd order overall. b) H2O2 is 2nd order, I – is 1st order, 3nd order overall. c) H2O2 is 0th order, I – is 1st order, H+ is 1st order, 3rd order overall. d) H2O2 is 2nd order, I – is 1st order, H+ is 0th order, 3rd order overall.

Problem: Consider a reaction with the following rate law Rate = k [C]2[D]3[E]-1 By what factor would the rate of the reaction increase if the concentration of [C] tripled, the concentration of D is increased by half and concentration of [E] doubled? A. 15.2 B. 12.9 C. 9.0 D. 6.5 E. 30.4
